Anyone tried laparoscopy for endometriosis?

Hello :)
I'm just curious if anyone has had a laparoscopy done for endometriosis and if it helped at all?
I'm scheduled for one in December as an effort to help with pain during sex, low sex drive, and ridiculous periods riddled with killer cramps, nausea, diarrhea and depressive pms :( 
Any insights are super appreciated!
